What causes foot bruises?
Most foot bruising is caused by a minor contusion or injury, such as from minor bumps, scrapes, trips or falls. You may find that you bruise more easily on your feet and legs than on other body parts. This is because those areas are generally more prone to injury and to the effect of gravity on blood flow. Easy bruising may simply be a familial, or inherited, tendency and not necessarily a cause for concern. Easy bruising is referred to as purpura simplex. However, frequent and unexplained bruising on your feet or any part of your body can be a sign of something more serious, such as a blood clotting disorder or a blood disease. Contact your healthcare provider to discuss your symptoms.
Injuries and trauma that can cause a foot bruise
Foot bruises can be caused by everyday injuries or more serious trauma including:
Blunt force or crush injury, such as a direct blow to the foot, dropping something on your foot, or crushing your foot under a very heavy object
Falling or tripping
Foot or ankle fracture
Sports injury, such as from running, skiing, snowboarding, or sports that involve person-to-person contact, including football and ice hockey
Walking, running or jumping on hard surfaces
Age, gender and lifestyle causes of a foot bruise
Easy or unexplained bruising on the feet can be caused by age, gender and lifestyle factors, such as:
Alcohol abuse (decreases blood clotting)
Female gender (women tend to bruise more easily than men)
Wearing the wrong size or fit of shoe
Serious underlying diseases and other conditions that can cause a foot bruise
A variety of diseases, disorders and conditions can cause bruising symptoms on many areas of the body. Some serious underlying causes of unexplained bruising or purpura include:
Autoimmune diseases, such as lupus and rheumatoid arthritis
Certain infectious diseases, such as meningitis, mononucleosis and measles
Hemophilia and Von Willebrand's disease (inherited bleeding disorders)
Thrombocytopenic purpura diseases (potentially life-threatening platelet disorders that cause problems with blood clotting)
Vitamin C deficiency (scurvy)
Medications that can cause bruising
The following medications may cause easy bruising or purpura on the feet and elsewhere on the body:
Anticoagulants (blood thinners), such as warfarin (Coumadin), enoxaparin (Lovenox), and heparin
Antidepressants, such as fluoxetine (Prozac) and paroxetine (Paxil)
Antiplatelet medications such as clopidogrel (Plavix)
Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin) and naproxen (Aleve, Naprosyn)
- Radiation or certain cancer chemotherapies
Always tell your doctor about any medications or treatments you are using, including prescription drugs, over-the-counter medications, dietary supplements, and herbal or alternative treatments.
What are the potential complications of a foot bruise?
Complications associated with foot bruises can be progressive and vary depending on the underlying cause. Because easy or unexplained bruising of the feet or any part of the body can be due to serious diseases, failure to seek treatment can result in complications and permanent damage. It is important to contact your healthcare provider when you have any kind of persistent or recurrent foot bruising. Once the underlying cause is diagnosed, following the treatment plan outlined by your doctor can lower your risk of potential complications including:
Compartment syndrome (severe swelling that leads to permanent muscle damage, disability, tissue death, and gangrene)
Myositis ossificans (bruised muscle that become calcified by growing bone cells instead of muscle cells as it heals, which can lead to chronic pain and reduced flexibility)
